Description

Optical record carrier reaches the method and apparatus in order to recording disk-like optical record carrier

Technical field

The invention relates to and a kind ofly have the optical record carrier that visually can detect pattern, and a kind ofly visually can detect pattern with one and be imprinted on method and apparatus on the optical record carrier.

Background technology

United States Patent (USP) notification number US 2004/0062179 explanation is a kind of can to form the optical disc recording apparatus that visually can detect pattern on a CD-RW discsCD-RW.This visually can be detected pattern and comprise and for example discern trade mark, a string character or its combination.This visually can be detected the resolution that pattern can detect with a human vision system and be printed.For example, this visually can detect pattern can every square millimeter 1 the resolution to hundreds of points printed (compare with mechanized data, it is that resolution with every square millimeter of number megabit grade is stored in the record carrier).Thus, the user does not need to see through the content that reading device comes the identification CD-RW discsCD-RW, and only needs simple vision detecting to get final product.

In general, the data recording on the CD-RW discsCD-RW is begun by the some radiuses near video disc central authorities, carries out along the groove to the external spiral development then.For as CD-RW discsCD-RW types such as CD and DVD, its specification requires under most of situation continuous data recording (this is the playability of guaranteeing in a read apparatus) between the data recording Origin And Destination.Therefore, at present already present can being printed on pattern on the radius in the recorded data outside at the pen recorder that printing on the video disc visually can be detected pattern.So, have visually detecting the shortcoming that pattern is printed on this position:

(1), visually can detect pattern and be positioned at video disc outer part branch ratio and be positioned near time in the middle of the video disc and account for more storage area with identical radius width;

(2) when print visually can detect pattern after, can't not destroy additional data under the original situation that visually can detect pattern;

(3) this mode of printing that visually can detect pattern not standard in the standard of general optical disk system.For example, this zone that visually can detect pattern comprises the data that can't be understood according to the optical disk system standard, therefore, when this zone of reading head accessing, can't produce probably and follow the rail signal, as DPD or recommend (push pull) signal, carry out servocontrol.And this may cause and traditional disc player between compatibility issue.To comprise this record video disc that visually can detect pattern and other and can only accept alternative compatibility between the disc player (non-knowledge disc player non-aware drives) of machine-readable data in order to possess, preferably possess following characteristic in design:

Do not make this effect that visually can detect pattern hinder the general player of this record carrier and the function of disc player;

Reduce this as far as possible and visually can detect reading of area of the pattern;

Visually can not detect on the zone of pattern and override new data because of carelessness comprising one.

The device of United States Patent (USP) notification number US 2004/0062179 visually can be detected pattern with this and be arranged in the video disc periphery.Yet this position shortcoming that visually can detect pattern is to occupy bigger area, thereby has dwindled the data storing capacity of video disc in principle.

Summary of the invention

In view of this, fundamental purpose of the present invention be to provide a kind of on an optical record carrier record one visually can detect method of patterning, it overcomes above-mentioned shortcoming to small part.

The optical record carrier that is provided comprises according to an aspect of the present invention:

Be positioned at this record carrier a recording layer place one visually can detect pattern;

This recording layer has a data area, in order to store:

Data, and

These data and this at least one general data organization system be normally with the form storage of mark (marks), and preferablely encoded by channel code (channel code);

This general data organization system does not also correspond to the physical address that comprises in this record carrier in this annulus that visually can detect pattern, and wherein at least a portion of this general data organization system and/or this data are to be arranged at the periphery that visually can detect pattern with respect to this.

The meaning that is arranged in the periphery is meant and is arranged in apart from the position of this record carrier rotation center than long radius.This optical record carrier can be a dishful of sheet-form optical record carrier, but also can be any other pattern can video disc shape optical record carrier the mode optical record carrier that is recorded or plays.On this kind record carrier, the record of data is along carrying out around the spiral fashion of rotation center or the track of concentric circles configuration.The atypical optical record carrier of this kind is credit card (CD-credit card) for example.

Organize the system of data to obtain in many ways.For example data can be configured to catalogue (it has list of pointers and points to the archives wherein organized for table ofcontent, TOC) form, be called again in some applications record management data (record management data, RMD).Another embodiment of this kind organization system is an archives economy, UDF for example, ISO9660, BDFS etc.In addition, these data also can be as video signal keeper application level (application level) tissues such as (video manager).In this data organization system, the archives of data or data for example can be organized into a menu framework (menu structure) or a link column (linked list).This data organization system does not need to use reference substance or index to select specific data item, and can use as the relevant settings such as label before the data item.In addition, this data organization system can be apt to add the specific arrangement of utilizing data.All data item wherein identical size of tool all for example, and arrange in sequence, make size can find at offset difference on the throne+n.S place for the data item n of S, deviate wherein only is provided in address table.

A kind of method that writes down video disc shape record carrier is provided according to a further aspect in the invention, comprises the following steps:

Printing one visually can be detected pattern, and this visually can detect pattern is an annular section that is configured in a recording layer of this optical record carrier;

In this recording layer record data with in order to organize at least one general data organization system of data, wherein the part this general data organization system or the part these data are the outer peripheral areas that are arranged in respect to this annular section.

A kind of device of recording optically record carrier is provided according to another aspect of the invention, and this device has one and is recorded in equipments of recording in the recording layer in order to the general data organization system of data and being organized data.

Equipments of recording in the recording layer of this device are joined by peace in addition and are printed one and visually can detect pattern to an annular section of a recording layer of this record carrier, wherein this general data organization system and do not correspond to physical address in this annular section.These equipments of recording can be recorded to these data of small part or this general data organization system in addition on the outer peripheral areas with respect to this annular section.

In a video disc shape optical record carrier according to the present invention, if with this visually can detect pattern be added in central authorities any the position and keep identical ring width, promptly Huan external diameter and the distance between internal diameter then can be saved the storage area.When this ring did not have to supply the data of this general data organization system addressing, disc player can not delivered to the zone that can't read to read head and go to attempt reading of data.

It is reported a kind of record carrier that visually can detect pattern that is provided with of Japanese patent publication JP2005135464 explanation.Attempting visually can to detect pattern to this for fear of device and be read as data, is a flaw block having the regional annotation that visually can detect pattern.Owing to can't come the mark defective with scope, therefore this visually can must be detected each occupied individual address of pattern and add in the defective row always.Need very lot of data thus.In fact, defect map in addition may be little to the zone that can't annotation be fit to the label size, for example radius size of 4mm.

In the present invention, this general data organization system and not corresponding to comprises the physical address that visually can detect in the annular section of pattern in this record carrier, thereby avoids device to attempt visually can to detect pattern to this being read as machine-readable data.Therefore, the method according to this invention does not need to provide defect management, can simplify control architecture.

This annular section does not need to be taken fully, basically as long as organize the general data organization system of data not corresponding to the physical address in this annular section on the video disc.

This optical record carrier for example can be a CD-RW discsCD-RW, CD-R for example, CD-RW, DVD+/-R, DVD+/-RW, BD-R, BD-RE, or HD-DVD.[DVD-RAM] etc. one of type.In addition, this optical record carrier also can be other media that can optical devices reads, as credit card CD, as long as data are to be arranged in this optical record carrier to be similar to the mode that is disposed in the CD-RW discsCD-RW, promptly shape or concentric circles mode dispose in the shape of a spiral around a rotation center.

Logging mode can variation on the citation form level, a for example burning (disc at once), multi-region section burning (multi-session), has or do not have logical over-write and at random continuous burning (sequentialwith or without logical overwrite and random).

This visually can be detected, and pattern is preferable to be arranged in the visible image window, and it visually can be detected the pattern both sides at this and comprise buffer zone.It is beneficial when the read head of an optical record carrier moves in this visible image window by the outside, desire data area.This read head enters one of buffer zone probably, makes optical record player produce the corrected rail signal that follows in read head position.Begin can be used as a buffer zone to what this visually can detect termination that benefit that pattern is arranged in the embodiment between first section and second section is last section and back one section.In addition, it also has at the pre-disc player (pre-fetch drive) that grasps, i.e. the disc player of reading of data in advance before the expection main frame will be inquired, the benefit of playback carrier.

Can carry out simultaneously user's position and duplicate (bit-copy).

Fig. 4 is the second embodiment synoptic diagram of the data content of a record carrier of the present invention.This second embodiment is to comprise user's data with different being in second section of first embodiment, and this general data organization system of second section is except from first section duplicates, and additionally add new archives economy information, in order to archives corresponding to the user's data in second section.

Fig. 5 is the 3rd an embodiment synoptic diagram of the data content of a record carrier of the present invention, it is in the embodiment shown in Fig. 3 and Fig. 4 different, and visually can to detect pattern (label) in this be to be recorded on the blank basically video disc, and be positioned near video disc place at the beginning, so its girth is quite little.Demonstrate one in this embodiment and intend making section (dummy session), add and intend making the EFM data, make visually can detect really pattern still the position outside predetermined radii (as 27mm).Thus, (the start up area) is far enough from the initiation region can to make this visually can detect pattern.This visually can be detected pattern and be surrounded by one second blank section, and real user's data can in after be recorded in outside this image section, perhaps be included in earlier in this second section.

Fig. 6 is the 4th an embodiment synoptic diagram of the data content of a record carrier of the present invention, and its demonstration has a plurality of embodiment that visually can detect pattern.Each visually can be detected pattern and all be surrounded by a pair of section.Each section comprises a start-up portion, a general data organization system and an ending (not being shown specifically).

Another embodiment of a record carrier of the present invention is shown among Fig. 7.In this embodiment, this record carrier comprises at least one section (image section 1), has part at the beginning, for example be called Intro (for DVD+R) or Border In Zone (for DVD-R), a general data organization system, visually can be detected a pattern and an ending, for example is called Closure (forDVD+R) or a Border Out Area (for DVD-R).This visually can detect pattern is to be recorded between the ending of this general data organization system and this at least one section, and at least one second section (record section 2) with data is the periphery that is recorded in this at least one section.

In an embodiment of the present invention, this visually can detect the part that pattern is a separate sections, is called the image section.This new section does not add archives itself, so do not have user's data recording in this section.Therefore, this general data organization system can not send read/write head to arrive in this zone.In the outside of image section, record the derivation (Lead-out) of general DVD-R or the ending of DVD+R.Show this example among Fig. 7.Though the image section does not have real archives size itself, but the most last block of section numbering (Last sector number) is pointed to and is comprised that this visually can detect the terminal position, zone of pattern, just looks like to use in this image section as the block numbering of essence.

Fig. 7 shows the zone of a burning number, and an image area segment record is outside this zone.This general data organization system in this image section is duplicating of last section, also be unique in this image section can be by the structure of access.

In addition, one visually can detect pattern can be recorded on the blank video disc shown in Figure 8, and it is near place of interior week.Enough far away in order to make this visually can detect pattern from this initiation region, add one before preferably this visually can detect pattern in this image section and comprise the buffer zone of intending making the EFM data.This buffer zone for example extends to the radius of 27mm.

As shown in Figure 9, can record is more a plurality of in surpassing a section visually can detect pattern.Therefore, each section is characterised in that having one visually can detect pattern, and the general data organization system of this section can visually can not detected the occupied regional addressing of pattern to this.

The embodiment of Fig. 3, Fig. 4, Fig. 5 and Fig. 6 is characterised in that logical data space is continuous.This helps ignoring on the video disc under this situation that visually can detect pattern with the whole bag of tricks duplicated record carrier to another record carrier.The embodiment of Fig. 7 and Fig. 8 is characterised in that logical data space is discontinuous, and this characteristic can effectively prevent copy.

On the other hand, the embodiment of Fig. 7 and Fig. 8 is characterised in that basic format is continuous, thereby makes adjacent derivation and importing follow mutually.

Another embodiment sees among Figure 10.Record carrier shown here comprises at least one section (record section 1), has at the beginning part (interior dish zone with import), this general data organization system (archives economy), this visually can detect a pattern (visible image) and an ending.This visually can detect pattern is to be recorded between the ending of this general data organization system and this at least one section.This at least one section further comprises data, and wherein at least a portion data (data field 1) are to be arranged in this visually can detect the periphery of pattern, and are positioned at this at least one section.

In the embodiment of Figure 10, this visually can detect pattern is between first and second data fields that are arranged in the section.In this embodiment, this logical data space is discontinuous, but because has a gap of not having a machine unscrambling data between this general data organization system and this first data field.

The another embodiment of this record carrier is DVD video disc (DVD-Video disc).In this embodiment, this data organization system is a DVD video signal keeper.As shown in Figure 11, this DVD video disc comprises that a video signal keeper is as a general data organization system on archives economy layer (forming a less important data organization system) and physical layer (physical layer).Therefore, as shown in figure 12, with regard to the DVD video disc, browsing of video disc is to handle in two stratum.Browsing of this video disc is to be handled by one first data organization system (this video signal keeper).In addition, this video disc comprises this low priority data organization system UDF and ISO9600.This video signal keeper who forms an application layer will be in following detailed description.

The position of archives is indicated by the low priority data organization system.Yet the video signal district browses on the whole video disc of this general data organization system (video signal keeper) control.This general data organization system solves the downward compatibility (backwards compatibility) of a visible image in this user data area.

Different persons with previous example, this DVD video disc is a single section record carrier.Discontinuous for fear of logical data space createed the virtual archives with the shared region overlapping of this visible pattern.Yet these virtual archives can't be corresponded to by DVD video signal keeper.

This low priority data organization system is configured in the label position with archives, but video signal keeper or menu framework can not point to the label archives.Simultaneously, the next unit pointer (Next-cell pointers) in NAV package (NAV package) can not point to the unit in the image section with the fast index (Fast Forward pointers) of changeing.

Figure 13 shows the general archives framework of DVD video disc.One DVD video disc comprises representative data (Presentation data), and it is real video signal and cd audio properties CD, and browsing data (Navigation data).In order to store this data, a DVD video disc comprises a video signal keeper (VMG) and video signal set of titles (VTS) under root directory.This video signal keeper controls whole video signal district, and each video signal set of titles comprises control and the menu information of playing true video signal content.

As shown in figure 13, each video signal set of titles can comprise a plurality of archives.These archives can be one of following type:

IFO type archives: these archives comprise an application message;

VOB type archives: these archives comprise the true video signal content of a series of one or more unit;

BUP type archives: these archives comprise the backup of an application message.

Also have the archives of other type also can be included in the video signal set of titles.1 to 99 video signal set of titles can be arranged, and each video signal set of titles can comprise 1 to 9 VTS-VOB archives.

On the DVD video disc, archives are by UDF1.02 and ISO9660 archives economy corresponding (UDF Bridge) in addition.All files all is recorded in (not segmentation) under the single catalogue.In fact, the order that records strictness of archives.

According to an aspect of the present invention, one visually can to detect pattern be to be provided in proper order on this video disc in the zone between former and later two archives with this, just this visually can be detected pattern is provided between the first archives terminal point and the second archives starting point archives to be connected in regular turn.

In the embodiment of Figure 14, video signal content archives are VTS-01-1.VOB herein, visually can detect pattern overlapping with this.In this example, data cell is video signal content archives VTS-01-1.VOB herein, corresponding to the archives (archives economy UDF) in this low priority data organization system.Yet this general data organization system (video signal keeper) does not also correspond to this archives.

As further shown in Figure 15, this video signal data is in each unit that is recorded on this video disc.The broadcast (playback of real-time videodata (scene)) of the real-time video signal data of a unit is represented in a unit. and each unit has a fixing ID numbering, and the length range of each unit all can to good a few minutes from being less than one second.(Program Chain PGC) defines the order that each unit is played to the refining of one program.One title (Title) can have one or more these PGC of PGC. that is connected and the unit can be played to carry out the selection of multi-angle (multi-angle), last stratum (parental level) or story line (story lines) in random order.Each PGC can have a forward and backward instruction (playing front/rear execution in PGC).And each unit can have unit instruction (cell-command), carries out when each broadcast Unit one.The details of this unit structure is shown among Figure 16.As shown in figure 16, each unit comprise video signal, message, subtitle information, with comprise represent control information (PCI) and data search information (DSI) browse package (navigation pack).This data search information comprises that one points to the pointer of next unit, carrying out the general regeneration of video signal content, and a pointer that points to unit far away, to carry out the fast rapid regeneration of video signal content.

The unit instruction is to exist according to circumstances with front/rear instruction.Can reach interaction by these instructions, for example unit can instruct and starts the broadcast of itself and ad infinitum play by sending a unit, presses on the telepilot up to the user " stop " till.Perhaps, unit instruction can require DVD player to skip a string location, even therefore these video signal fragments are present on the DVD, but also can not be played always.Unit one comprise one or more video signal object unit (Video Object Units, VOBU).。Each VOBU is 0.4 second to 1 second a reproduction time length, and comprises package (2048bytes).Video signal, message, subtitle etc. are multitasking in VOBU.Each VOBU browses package by one and begins, and it comprises two packages:

PCI: represent control information (Presentation Control Information)

DSI: data search information (Data Search Information)

In another embodiment of the present invention, as shown in figure 16, a video signal content archives unit and this visually can be detected pattern overlapping.Perhaps this visually can be detected pattern and replaces one or more unit, ID Unit 3 in this embodiment conversely speaking.The unit instruction is all used so that video disc player is avoided in the label zone with the DSI characteristic.In the unit before the viewing area, add a skip instruction (skipcommand) to skip the dummy unit that this visually can detect the pattern position place.Simultaneously, next unit pointer among arbitrary DSI and fast commentaries on classics pointer also can visually can not be detected the position of pattern corresponding to this.

In another embodiment, as shown in figure 17, this visually can be detected pattern and replace a video signal set of titles.In brief, this programme can multiple aspect avoids label zone on the DVD video disc by access:

In low priority data organization system aspect, the label archives are to be addressed to the label position.There are several schemes can avoid this and have the zone that visually can detect pattern, make that this zone will never be by access in fact;

One comprises that this complete video signal set of titles that visually can detect pattern can not corresponded to by root menu;

One comprises that one or more archives in this video signal set of titles that visually can detect pattern can not corresponded to by this general data organization system;

One comprises that one or more unit in this video signal set of titles that visually can detect pattern can not corresponded to by arbitrary program chain, can not corresponded to by arbitrary NAV package yet.Next unit pointer in the NAV package can be ignored this label zone with the fast unit pointer that changes.

This have the zone that visually can detect pattern or " visible image " zone can comprise an initiating terminal and terminal buffer zone.This buffer zone can comprise a traditional video data stream.

The scheme that goes out mentioned herein is specially adapted to provide a label to the DVD+R and DVD-R video disc that use as video disc.This programme has avoided general application and general disc player to go to access label zone.

These designs are equally applicable on other type video disc, as BD and HD-DVD laser discsLD, can detect pattern to provide visually.

Figure 18 shows an example of a record carrier of the present invention, wherein this visually can to detect pattern be to be arranged in the visible image window, it visually can be detected the pattern both sides in this and include a buffer zone.
